Effectiveness of botulinum toxin B in the treatment of drooling.

The aim of this audit was to assess the effectiveness of botulinum toxin B (NeuroBloc(®), Eisai Ltd.) in the treatment of drooling. Over a period of 18 months patients treated with NeuroBloc(®) botulinum toxin (BTX) for serious drooling (drooling score more than 7) were invited to complete a questionnaire on their experience of drooling and the impact of treatment.

Does the method of resection affect the margins of tumours in the oral cavity? Prospective controlled study in pigs.

It is important to obtain tumour-free resection margins in patients with oral cancer. Pathological processing is known to cause tissue to shrink, which affects the reported margins, and it is postulated that the method of resection also has an effect. We marked standardised simulated lesions on the tongues of 15 live anaesthetised pigs and divided each lesion into four equal sections.

Parotid surgery for benign tumours.

Purpose: The majority of parotid tumours are benign, making parotid surgery a compromise between adequate tumour excision and preservation of function and facial harmony. Besides the traditional superficial or total parotidectomy, less invasive techniques have been described with similar recurrent rates. The aim of this review is to assess the evidence in the published literature and to summarise the advantages and disadvantages of the available techniques.
